Pool Closing & Winterization
Pool Closing Services
Winterizing your pool properly is one of the most important steps to protecting your investment. When done wrong, freezing temperatures and idle systems can cause costly damage. Let our team handle it right the first time.
What's included:
- Equipment disassembly and winterization: We carefully disconnect and drain pumps, heaters, filters, and other equipment to prevent freezing and cracking.
- Draining and chemical balancing: We adjust water levels and apply winter chemicals to prevent algae growth and protect surfaces.
- Cover installation: We securely install your pool cover, ensuring it fits properly and will hold up against harsh weather.
The Real Cost of Skipping Winterization
A single hard freeze can cause thousands of dollars in damage to pools that weren't properly closed. Here's what's at stake:
Burst Pipes & Cracked Equipment
Water left in plumbing lines expands when it freezes. This can crack PVC pipes, split pump housings, and damage filter tanks — repairs that easily run into the thousands.
Algae & Staining
Without proper winterization chemicals, algae can bloom unchecked over the off-season, leading to stained surfaces and a lengthy, chemical-heavy cleanup in spring.
Structural Surface Damage
Improper water levels under a cover combined with freeze-thaw cycles can stress plaster, tiles, and coping — accelerating wear that could have been avoided.
Higher Spring Costs
An improperly closed pool almost always requires extra service at opening — more chemicals, more labor, and sometimes emergency repairs. The cost of a proper close always pays off.

When should I close my pool in Virginia or Maryland?
In the DMV area, we generally recommend closing your pool between mid-September and the end of October, once daytime temperatures are consistently below 65°F. Closing too late risks freeze damage to pipes and equipment when the first hard frost hits.
If you want a specific recommendation based on your pool type and location, contact us and we'll help you pick the right window.
What happens if I skip winterizing my pool?
Skipping winterization is one of the most costly mistakes a pool owner can make. Without proper closing:
- Water left in pipes, pumps, and filters can freeze and crack equipment
- Algae can bloom extensively over winter, requiring expensive treatment in spring
- Unbalanced chemistry can stain and damage pool surfaces
- Covers may fail or be difficult to secure without proper water leveling
The cost of professional winterization is a fraction of what emergency repairs can cost after a hard freeze damages your equipment.
What is included in your pool closing service?
Our pool closing service covers everything needed to protect your pool over the winter:
- Cleaning the pool, balancing water chemistry, and applying winter chemicals
- Adjusting water level for cover installation
- Draining and blowing out all plumbing lines to prevent freeze damage
- Disconnecting, draining, and winterizing pumps, filters, and heaters
- Securing and installing your winter safety cover
Can you close my pool if I have an automatic cover?
Yes. We work with all types of pool covers, including automatic covers. We'll clean the cover, ensure it's properly secured, and perform all necessary winterization steps around it. If your automatic cover system needs a service check before winter, we can handle that at the same time.

“Beltway Pools installed a new concrete base and replaced much of our plumbing equipment and heater 5 years ago. Since then they have serviced the pool with opening and closing. They are a very good and dependable team, always arriving on time. Rob is always available if you need to speak with him, and can advise on future needs for your system.”

“I'm very glad I found Beltway Pools. I needed opening and closing when my old provider stopped servicing the area. Beltway is much better at communication, doesn't apply sales pressure, has lots of options to fit your needs and budget. Glad to be working with them. Services Service not listed”

“Robert, Dragan, and their crew did an amazing job. I spent months getting quotes from several companies. Beltway pools’ wasn’t the least expensive but I felt that they were the most straightforward. Instead of just pushing me to replace everything, broken or not, they had more of a wait and see approach. They worked with us to come up with a plan to get the pool back operational as economically as possible, and then work on our “wants” list. Our pool had been closed for almost 10 years due to damage caused by changes in drainage made by construction in the neighborhood. At 65k gallons, the pool is extremely large and even more expensive than your average pool remodel. They removed several feet of debris, drained and scrubbed the pool, replace the tile & coping, the pool equipment, repairing equipment that could be fixed, and replacing what needed to be prioritized for upgrades. They did the entire project over a couple of weeks. They stated on time, stayed on budget, and were an absolute pleasure to work with. I have kept them on to handle the pool maintenance including opening and closing the pool and keeping it clean during the summer. Their prices are fantastic and as I mentioned, Robert isn’t going to sell you something that you don’t need. He’s going to help your pool become enjoyable again.”
